Acetabular Cup Orientation System

Page Type
Product Code
Definition
The acetabular cup orientation system is intended to be used as a surgical instrument to assist in the intra-operative orientation of acetabular cup components used with total hip arthroplasty. The device utilizes anatomic landmarks of the pelvis that are clearly identifiable on pre-operative imaging scans.
Physical State
A patient-matched acetabular guide, made of polymeric material and with a patient-matched surface that is congruent to the mating acetabular surface. May be manufactured through an additive manufacturing process.
Technical Method
The device consists of a software component that generates a pre-operative plan based on the medical imaging data and a hardware component, the patient-matched guide that is positioned onto/within the acetabulum by mating the patient-specific contact surface to its corresponding anatomical surface. The guide is used to place an alignment pin at/near the acetabular rim in a pre-operatively desired orientation. The alignment pin is used as a visual reference to assist in the intra-operative orientation of the acetabular component during THA, so the surgeon may visually ensure that the orientation of the alignment pin matches the normal direction of the acetabular component.

CFR § 888.3350 Hip joint metal/polymer semi-constrained cemented prosthesis

§ 888.3350 Hip joint metal/polymer semi-constrained cemented prosthesis.

(a) Identification. A hip joint metal/polymer semi-constrained cemented prosthesis is a device intended to be implanted to replace a hip joint. The device limits translation and rotation in one or more planes via the geometry of its articulating surfaces. It has no linkage across-the-joint. This generic type of device includes prostheses that have a femoral component made of alloys, such as cobalt-chromium-molybdenum, and an acetabular resurfacing component made of ultra-high molecular weight polyethylene and is limited to those prostheses intended for use with bone cement (§ 888.3027).

(b) Classification. Class II.
